ASTRODON FILTERS

For astrophotography, our LRGB filters simplify imaging by allowing you to take one exposure time for each color, only one corresponding dark exposure time and nearly equal color combine weights in post-processing. The resulting color balance is superb, which is why so many of the top imagers now use Astrodon LRGB filters. With our designs, we’ve eliminated halos around bright stars that detract from the beauty of your galaxy or nebula.

Our NARROWBAND filters set the highest, consistent performance level, and are spectrally narrower than most other filters, leading to the best contrast and faintest structures in your nebula. We put our performance guarantee of >90%T at the emission line on every box.

Our UVBRI and Sloan PHOTOMETRIC filters are 100%-coated using no colored glass for long-term durability that is so critical for consistent, long-term research. They have the highest throughputs available for better signals and fainter objects. They are becoming widely accepted in professional observatories in sizes up to 150 mm. Some of these larger filters are used on the famous Palomar 200″ telescope, at the MacDonald Observatory, Las Cumbres Observatory of Global Telescopes, AAVSO and universities and research organizations worldwide.

All Astrodon astrophotography filters are manufactured in the U.S. with superb quality control using 100% hard-oxide sputtered coatings. You pay extra for Astrodon filters because you expect and receive all the benefits that our highest performance and great durability provides. You have invested considerable time and money in your telescope system. Filters are a critical part of your system. They are the “spark plugs” that make the “engine” go. Step up to Astrodon and see the difference yourself.
